An Iranian woman holds her national flag during a rally outside the former US embassy in Tehran on November 4, 2009 to mark the storming of the American embassy by Iranian students 30 years ago. Thousands of Iranians staged the noisy anti-US rally in central Tehran as riot police armed with batons and firing teargas moved in as several hundred opposition supporters attempted to stage an anti-government protest.
